Geometric Dimensioning and Tolerancing
Geometric Dimensioning and Tolerancing (GD&T) is a quality control system used in manufacturing and engineering to ensure parts fit together correctly. It defines the allowable variations in shape, size, and location of features on a part. By using symbols and precise measurements, GD&T helps convey complex design requirements clearly and accurately, allowing engineers and manufacturers to understand how much deviation from the ideal is acceptable. This ensures parts can be made efficiently while meeting functional requirements, ultimately improving product quality and performance.

Geometric Dimensioning and Tolerancing (GD&T) is a system used in engineering and manufacturing to communicate the size, shape, and allowable variations of physical parts. It goes beyond simple measurements to define the geometric features of a part, such as flatness, roundness, and orientation. GD&T uses symbols and annotations on technical drawings to specify these characteristics and ensure parts fit together correctly during assembly. This ensures consistency in production, reduces waste, and enhances product quality by providing clear guidelines on how parts should be manufactured and inspected.
